ST. LOUIS SIEVE.

SPECIFICATION forming part of Letters Patent No. 224,598, dated February 17, 1880.

Application filed December 27, 1879. i

REN, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Sieves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My improvement relates to the joint between the hoop and wire cloth or gauze and it consists in forming near thebottom of the hoop, at the outer side, a groove, into which the edge of the gauze is forced and retained by a wire or string. Over the joint the foot band or batten is secured in the ordinary manner.

This improvement applies to both metal and wooden hoop-sieves. i

In the drawings, Figure 1 shows a metal sieve, half in side view and half in section, with a view of the interior. Fig. 2 is an en larged detail section of the joint. Fig. 3is an enlarged detail section of the joint as applied to a wooden sieve.

A is the hoop. This has an outer groove, a, formed in it at the lower edge, to receive the outer edge, I), of the gauze or straining-cloth B. (Shown in dotted lines.) The edge I) is held in the groove a by a surrounding wire or string, 0, which occupies the groove outside the gauze.

The foot-hoop is seen at D. It covers the groove, and serves as a foot for the sieve, to preserve the gauze from wear when the is down.

In the metal sieve the foot D is fixed on by solder. In the wooden sieve the foot or bat ten D is tacked on, usual.

Having described my invention, what I 40 EDWARD J. MOGURREN.
